Ecological potential

Goal to be achieved by 2015 for artificial water bodies and heavily modified water bodies in accordance with the Water Framework Directive 2000/60/EC. The ecological potential of an artificial or heavily modified water body is defined with reference to the most comparable type of surface water bodies. Compared to the values of quality elements for the most comparable type of surface water bodies, the values of good potential take into account the artificial or heavily modified characteristics of the water body. The ecological potential has four classes: good, moderate, poor and bad. Meanwhile the chemical objective remains unchanged.
